' 6 Claims. (Cl. 10813) metal is high. Hence, the roof has a tendency to break away atits seams or 'joints under certain .temperature changes. 'Thus,'even a newly laid copper roof is liable to leak where a considerable temperature change occurs. I It is, therefore, one of the salient objects of my invention to provide a novel methodof laying a copper roof, whichwill not break away or crack under severe temperature changes, so that a weather-tight roofwill be had under all conditions. Another important object of my invention is to provide a copper or other metal roof formed fromdifierent layers of sheet metal, in which the various layersare all sweated or otherwise soldered together throughout their entire area, whereby to produce (in effect) a continuous onepiece roof, which will expand and contract as a single unit, so that all danger of breaks is eliminated.

A further object of my invention is to provide a copper or other metal roof formed from different layers of sheet metal with the different layers sweated together throughout their entire area, thesheets of one layer being arranged at an angle to the sheets of an adjacent layer, so that the overlapping portions ofthe sheets of the different layers will be out of alinement for structural strength.

A further object of my invention is to provide a metal roof formed from a series of different layers of metal strips arranged in overlapping relation, with means for firmly anchoring the initial layer to the roof bed, and the other layers together to form a unitary roof construction.

A still further object of my invention is to provide a novel method of laying a roof, which consists in: first, taking sheets of copper or other metal and coating the entire area of the sheets with a skin of solder or like material; second, laying the coated sheets in overlapping relation to form one layer; third, anchoring the sheets .to the roof; fourth, laying a second. layer of the sheets on the first layer and applying heat to firmly unite the first and second layers together throughout their entire area by the solder. 7

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a fragmentary perspective View of a roof constructed in accordance with my invention, the various layers of the roof being shown arranged in stepped relation to permit an understanding of the invention to be had.

Figure 2 is an enlarged fragmentary perspective View of one of the strips of the sheet metal, showing the same tinned on its opposite sides.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts thoughout the several views, the letter R. generally indicates my improved copper roofing applied to any preferred type of roof bed, or support, 5. This roof bed can be formed from wooden planks or in any other desired way, and thus the bed 5 forms no part of the present invention.

In accordance with my invention, I lay a series of layers 6, l, and 8 of sheet metal strips to form the improved roof. While I have specified three layers, it is to be understood that two or any preferred number of layers can be provided without departing from the spirit of the invention, according to the quality of the roof desired, or the amount of money the purchaser wants to place on the roof.

The first layer 6 includes a plurality of sheet metal strips, 9, which are placed longitudinally of the roof in overlapping relation, and these strips are firmly secured in place to the roof bed 5 in any preferred manner, such as by the use of fastening elements II].

In laying the first layer 6, I prefer to utilize a longitudinally extending half-strip I l at the lower edge of the roof and over the gutter l2 of the roof. This gives an additional thickness at a needed point right at the start, it being noted that the full-width strip 9 is placed entirely over the halfwidth strip II.

The second layer I also consists of sheet metal strips l3, which are arranged transversely of the roof in overlapping relation, as is clearly illustrated in Figure 1 of the drawing.

Where the third layer is used, sheet metal strips 14 are arranged at right angles to the strips l3 and longitudinally of the roof in overlapping relation. Thus, the strips 9 and the strips Id of the Before the various strips of the layers are laid in place, the same are tinned on opposite sides with a thick skin of solder orthe like l5, and after the second layer is placed on the first layer, heat is applied thereto so as to melt the solder I 5'and firmly unite the strips l3 of the second layer 6. i V 1 When the strips M of the third layer are laid,

heat is'applied'thereto, so as to melt'the solder one another, it is to be understoodthat the strips of thelayers can be run diagonally relative to one another; r V

The method-of applying the sheet metal has been explained for roofingonly, but it is to be understood that theprinciples of my invention can be applied in the forming of. tanks, tubes,

etc.

I do not limit myself as to'the exact position of the various forms'of the strips relative to one another. Thus the layer 6 could be utilized for the layer 8, and vice versa. Changes in details'can be made without departing from the spirit or the scope of this invention, but what I claimas new is: f

The method of laying a sheet metal roof, which consists in: first, coating the opposite sides of metal strips with solder; second, laying the strips in overlapping relation and anchoring the strips to a roof; third, laying asecond' layer of and, fourth, applying heat to the second layer to melt the solder, so that the layers will be firmly united throughout their entire area.
